Abstract

In a multi-roll stand having laterally supported working rolls 4, each working roll 4 is supported at at least one side against a radially unmounted lateral intermediate roll 5, which, for its part, is supported against a first, radially mounted supporting roller 6 and a further, radially unmounted intermediate roll 7. The further intermediate roll 7 is supported against a second, radially supported supporting roller 8 and against that intermediate roll 3 of a six-high roll stand which supports the working roll 4 vertically or against the supporting roll of a four-high roll stand. By virtue of this type of lateral support, the risk of slip between the working roll 4 and the lateral intermediate roll 5 supporting it is reduced because a torque is transmitted to the intermediate roll 5 from the intermediate roll 3 or supporting roll of the roll stand via the further lateral intermediate roll 7. In addition, the space for the lateral support can be better utilized for an increase in the supporting forces.

Description

Die Erfindung bezieht sich auf ein Vier- oder Sechs-Walzengerüst mit seitlich abgestützten Arbeitswalzen, wobei jede Abstützung eine radial nicht gelagerte, an der zugeordneten Arbeitswalze anliegende, seitliche Zwischenwalze und zwei radial gelagerte Stützrollen aufweist.The invention relates to a four- or six-roll stand with laterally supported work rolls, each support having a radially non-supported, intermediate work roll lying on the associated work roll and two radially mounted support rollers.

Bei Walzgerüsten dieser Art sind die Arbeitswalzen, die Stützwalzen und gegebenenfalls die Zwischenwalzen entweder in einer gemeinsamen vertikalen Ebene angeordnet, wobei dann auf beiden Seiten der Arbeitswalzen Abstützungen vorgesehen sind, oder die Arbeitswalzen und gegebenenfalls die Zwischenwalzen sind gegenüber der von den Achsen der Stützwalzen bestimmten vertikalen Ebene seitlich versetzt, wobei dann eine einseitige Abstützung der Arbeitswalzen und gegebenenfalls der Zwischenwalzen genügt. Der Grund für den Einsatz der Abstützungen besteht darin, ein unkontrolliertes horizontales Biegen der Arbeitswalzen zu vermeiden. Insbesondere ist die seitliche Abstützung bei Arbeitswalzen notwendig, deren Verhältnis zwischen dem Durchmesser der Arbeitswalze und deren Nutzlänge 1 : 4 übersteigt. Mit den Abstützungen lassen sich allerdings auch die Arbeitswalzen kontrolliert horizontal biegen , um Einfluß auf den zu walzenden Bandquerschnitt zu nehmen.In roll stands of this type, the work rolls, the support rolls and, if appropriate, the intermediate rolls are either arranged in a common vertical plane, in which case supports are provided on both sides of the work rolls, or the work rolls and, if appropriate, the intermediate rolls are opposite the vertical one determined by the axes of the support rolls Level laterally offset, then one-sided support of the work rolls and possibly the intermediate rolls is sufficient. The reason for using the supports is to avoid uncontrolled horizontal bending of the work rolls. In particular, the lateral support is at Work rolls necessary, the ratio between the diameter of the work roll and its useful length exceeds 1: 4. With the supports, however, the work rolls can also be bent horizontally in a controlled manner in order to influence the strip cross section to be rolled.

Die Abstützungen bestehen in der Regel jeweils aus einer verhältnismäßig dicken, an der zugehörigen Arbeitswalze anliegenden seitlichen Zwischenwalze und zwei radial gelagerten Stützrollen, an denen die radial nicht gelagerte seitliche Zwischenwalze abgestützt ist (GB-PS 1 488 796; GB-PS 1 329 971). Die Stützrollen können jeweils aus einer durchgehenden Rolle oder aus in einer Reihe angeordneten kürzeren Rollen bestehen. Der Grund für die Ausbildung der Abstützung in Form einer verhältnismäßig dicken seitlichen Zwischenwalze und von zwei diese abstützenden Stützrollen besteht darin, daß der Raum, in dem diese Abstützung unterzubringen ist, insbesondere dann beengt ist, wenn das Durchmesserverhältnis zwischen der Arbeitswalze und der senkrecht benachbarten Zwischen- oder Stützwalze klein ist, zum Beispiel nur 1 : 3 beträgt. In diesem Fall entsteht ein keilförmiger Raum, der einerseits durch das zu walzende Band und andererseits durch die Mäntel der Arbeitswalze und Zwischenwalze bzw. Stützwalze begrenzt ist. Unter diesen Bedingungen lassen sich die erforderlichen seitlichen Abstützkräfte nur beim Einsatz verhältnismäßig dicker seitlicher Zwischenwalzen aufbringen, weil nur dann genügend Raum zur Verfügung steht, um entsprechend groß dimensionierte Stützrollen unterzubringen, die die erforderlichen Abstützkräfte aufnehmen können. Seitliche Abstützungen mit verhältnismäßig dicken seitlichen Zwischenwalzen mit einem entsprechend großen Massenträgheitsmoment wirken sich aber ungünstig aus, da die Übertragung der Drehbewegung von der Arbeitswalze ausgeht und es deshalb in der Beschleunigungsphase zu einem Schlupf zwischen den Walzen kommen kann. Dadurch können Oberflächenschäden entstehen, die sich auf das Walzgut übertragen.The supports generally consist of a relatively thick side intermediate roller, which is in contact with the associated work roll, and two radially mounted support rollers, on which the radially non-supported side intermediate roller is supported (GB-PS 1 488 796; GB-PS 1 329 971) . The support rollers can each consist of a continuous roller or of shorter rollers arranged in a row. The reason for the formation of the support in the form of a relatively thick lateral intermediate roller and two supporting rollers supporting it is that the space in which this support is to be accommodated is particularly narrow when the diameter ratio between the work roller and the perpendicularly adjacent intermediate - or backup roller is small, for example only 1: 3. In this case, a wedge-shaped space is created, which is limited on the one hand by the strip to be rolled and on the other hand by the jackets of the work roll and intermediate roll or backup roll. Under these conditions, the required lateral support forces can only be applied when using relatively thick lateral intermediate rollers, because only then is there enough space available to accommodate correspondingly large support rollers that can absorb the required support forces. Lateral supports with relatively thick lateral intermediate rolls with a correspondingly large mass moment of inertia have an unfavorable effect, however, since the transmission of the rotary movement originates from the work roll and therefore a slip between the rolls can occur in the acceleration phase. This allows Surface damage occurs, which is transferred to the rolling stock.

Im übrigen kann bei großen seitlichen Kräften der keilförmige Raum für die Unterbringung der seitlichen Abstützung wegen der verhältnismäßig groß zu dimensionierenden Abstützrollen zu klein sein.Moreover, with large lateral forces, the wedge-shaped space for accommodating the lateral support can be too small because of the support rollers which are to be dimensioned relatively large.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Mehrwalzengerüst die seitlichen Abstützungen der Arbeitswalzen dahingehend zu verbessern, daß die Stützfähigkeit der Abstützung verbessert ist und die Gefahr des Schlupfes zwischen den sich drehenden Teilen der seitlichen Zwischenwalze vermindert ist.The invention has for its object to improve the lateral supports of the work rolls in a multi-roll stand in such a way that the support capacity of the support is improved and the risk of slippage between the rotating parts of the lateral intermediate roll is reduced.

Diese Aufgabe wird erfindungsgemäß bei dem Mehrwalzengerüst der eingangs genannten Art dadurch gelöst, daß die Abstützung eine weitere seitliche Zwischenwalze aufweist und daß die eine seitliche Zwischenwalze an einer der beiden Stützrollen und der weiteren seitlichen Zwischenwalze abgestützt ist, die an der anderen Stützrolle und bei einem Vierwalzengerüst an deren Stützwalze und bei einem Sechswalzengerüst an deren Zwischenwalze abgestützt ist.This object is achieved in the multi-roll stand of the type mentioned in that the support has a further lateral intermediate roller and that one side intermediate roller is supported on one of the two support rollers and the further side intermediate roller, which is supported on the other support roller and in a four-roll stand is supported on the support roller and in the case of a six-roll stand on the intermediate roller.

Aufgrund des Einsatzes der weiteren seitlichen Zwischenwalze und deren besonderer Abstützung wird erreicht, daß bei verhältnismäßig kleinem Durchmesser der Zwischenwalzen genügend Freiraum für die Unterbringung entsprechend groß dimensionierter Stützrollen verbleibt, wobei die Stützrollen eigens über die jeweilige Zwischenwalze angetrieben werden. Dadurch wird die Funktions- und Stützfähigkeit der Abstützung verbessert. Die Gefahr des Schlupfes zwischen der Arbeitswalze und der unmittelbar an ihr anliegenden seitlichen Zwischenwalze wird vermindert, weil zum einen die Zwischenwalze ein geringeres Massenträgheitsmoment hat und zum anderen auf die Zwischenwalze über die weitere Zwischenwalze von der Stützwalze bzw. Zwischenwalze des Walzgerüstes ein zusätzliches Drehmoment übertragen wird. Schließlich ergibt sich auch für die die Arbeitswalze unmittelbar abstützende Walze des Walzgerüstes über die weitere Zwischenwalze eine seitliche Abstützung. Dies ist besonders bei einem Sechswalzengerüst von Vorteil, bei dem die Zwischenwalze einen verhältnismäßig kleinen Durchmesser hat.Due to the use of the further lateral intermediate roller and its special support, it is achieved that with a relatively small diameter of the intermediate rollers there is sufficient space for accommodating correspondingly large supporting rollers, the supporting rollers being driven specifically by the respective intermediate roller. This improves the functionality and support capacity of the support. The risk of slippage between the work roll and the side intermediate roll lying directly against it is reduced because, on the one hand, the intermediate roll has less Has moment of inertia and on the other hand, an additional torque is transmitted to the intermediate roller via the further intermediate roller from the support roller or intermediate roller of the roll stand. Finally, there is also lateral support for the roll of the roll stand that directly supports the work roll via the further intermediate roll. This is particularly advantageous in the case of a six-roll stand in which the intermediate roll has a relatively small diameter.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel schematisch darstellenden Zeichnung näher erläutert.The invention is explained in more detail below with reference to a drawing schematically illustrating an exemplary embodiment.

In einem Walzenständer 1 eines Sechswalzengerüstes sind zwei Stützwalzen 2, zwei Zwischenwalzen 3 und zwei Arbeitswalzen 4 gelagert. Jeder Arbeitswalze 4 ist auf jeder Seite eine seitliche Abstützung zugeordnet.In a roll stand 1 of a six-roll stand, two backup rolls 2, two intermediate rolls 3 and two work rolls 4 are mounted. A lateral support is assigned to each work roll 4 on each side.

Jede Abstützung weist zwei Stützrollen 6,8 auf, die jeweils aus einer durchgehenden Rolle oder aus Rollenabschnitten bestehen können. Die beiden Stützrollen 6,8 sind radial in einer Stützrollenaufhängung 9 gelagert. Die Stützrollenaufhängung 9 ist mittels eines einstellbaren Abstützelementes 10 in Richtung auf die Arbeitswalze 4 einstellbar.Each support has two support rollers 6, 8, which can each consist of a continuous roller or of roller sections. The two support rollers 6, 8 are mounted radially in a support roller suspension 9. The support roller suspension 9 can be adjusted in the direction of the work roll 4 by means of an adjustable support element 10.

Jede Abstützung weist ferner zwei seitliche Zwischenwalzen 5,7 auf, die im Durchmesser wesentlich kleiner als die Arbeitswalze 4 und die Stützrollen 6,8 sind. Diese Zwischenwalzen 5,7 sind radial nicht gelagert. Die erste seitliche Zwischenwalze 5 stützt die Arbeitswalze 4 seitlich ab. Sie ist ihrerseits an der ersten Stützrolle 6 und an der zweiten seitlichen Zwischenwalze 7 abgestützt. Die zweite seitliche Zwischenwalze 7 ist ihrerseits an der zweiten Stützrolle 8 und an der benachbarten Zwischenwalze 3 des Walzgerüstes abgestützt.Each support also has two lateral intermediate rolls 5, 7, which are considerably smaller in diameter than the work roll 4 and the support rolls 6, 8. These intermediate rollers 5, 7 are not supported radially. The first lateral intermediate roll 5 supports the work roll 4 laterally. For its part, it is supported on the first support roller 6 and on the second lateral intermediate roller 7. The second lateral intermediate roller 7 is in turn on the second support roller 8 and on the adjacent intermediate roller 3 of the Supported roll stand.

Bei dieser Ausführung ist es möglich, die die Zwischenwalze 7 abstützende erste seitliche Zwischenwalze 5 trotz der beengten Verhältnisse in dem keilförmig von dem zu walzendenden Band 11 und den Walzen 3,4 des Walzgerüstes begrenzten Raum wirksam abzustützen, weil die erste seitliche Zwischenwalze 5 zum einen an der verhältnismäßig groß dimensionierten ersten Stützrolle 6 und zum anderen an der im Durchmesser kleinen zweiten seitlichen Zwischenwalze 7 abgestützt wird, die ihrerseits aber an der verhältnismäßig groß abgestützten zweiten Stützrolle 8 und der Zwischenwalze 3 des Walzgerüstes abgestützt ist. Neben diesem Vorteil wird mit der erfindungsgemäßen Konstruktion außerdem erreicht, daß von der Zwischenwalze 3 des Walzgerüstes über die zweite seitliche Zwischenwalze 7 ein Drehmoment auf die erste seitliche Zwischenwalze 5 übertragen wird, so daß nicht länger auf diese Zwischenwalze 5 nur über deren Abstützstelle an der Arbeitswalze 4 ein Drehmoment übertragen wird. Die Gefahr des Schlupfes, insbesondere beim Beschleunigen des Walzgerüstes, ist dadurch erheblich vermindert.In this embodiment, it is possible to effectively support the first lateral intermediate roller 5 supporting the intermediate roller 7 despite the cramped conditions in the space delimited by the strip 11 to be rolled and the rollers 3, 4 of the roll stand, because the first lateral intermediate roller 5 on the one hand is supported on the relatively large dimensioned first support roller 6 and on the other hand on the small, second lateral intermediate roller 7, which in turn is supported on the relatively large supported second support roller 8 and the intermediate roller 3 of the roll stand. In addition to this advantage, it is achieved with the construction according to the invention that a torque is transmitted from the intermediate roll 3 of the roll stand to the first lateral intermediate roll 5 via the second lateral intermediate roll 7, so that it is no longer transmitted to this intermediate roll 5 only via its support point on the work roll 4 a torque is transmitted. The risk of slippage, especially when accelerating the roll stand, is considerably reduced.
